The correct answer is Birth.
The two elements that raise population size are natality—the number of people who are added to a population over time as a result of reproduction—and immigration—the movement of people into a location. Most births are to folks who are young adults or older. Even at replacement fertility levels (when each woman has approximately an average of two children), there will be more births than deaths if the proportion of young adults to older adults is higher where mortality is highest. Immigration and birth rates lead to population growth. The population shrinks as a result of death rates and emigration. A population that has a negative growth rate is one in which there are more deaths and emigrants than births.

What happens when the number of organisms in an environment is higher than the carrying capacity? A. The population will increase slowly. B. The population remains the same. C. The population will increase quickly. D. The population will decrease.
Answer:
When the number of organisms in an ecosystem exceeds the carrying capacity, the population will decrease.
Please see the explanation!
Explanation:
The maximum that can be maintained forever is the concept of "carrying capacity." This can only be rationally understood as the highest number that can be maintained using exclusively renewable resources. It can only be exceeded by using resources more quickly than they can be replenished.
The population gets wiped out (not by old age mortality) back to the number that can be maintained using only renewable resources when those resources become limited, as they must by definition.
Remember that every population is trying to expand, therefore if a species finds a resource that it can use more quickly than it replenishes, the population will undoubtedly expand to use that newly discovered capability. Another way to put this is to say that when the species average is x newborns and the subsistence supply is steady, (x-2)/x children must perish. Less offspring must perish than the formula predicts when the species finds a new non-renewable source of food, increasing the subsistence supply.
It should be noted that there are plainly too many people in the world. Over the past few hundred years, we have developed various technologies that have increased subsistence extraction and decreased waste. Of course, we have multiplied to occupy that additional space. In order to provide enough food to sustain 7+ billion people at once, we need fossil fuels and a number of other resources that do not replenish as quickly as we use them. The last time humanity were able to maintain their population on exclusively renewable resources, there were less than 1 billion people. Be aware that we have never been able to raise subsistence production as quickly as we have sought to increase our population. We have always had an average of too many infants, as seen by the starvation-related child mortality that affects some populations.
Thank you,

What is murder?This is a deliberate act of killing another being, especially human.This is a crime against humanity and it is punishable.
Guilty means to be responsible for a dishonest act especially judged to have committed a crime.
Evidence which shows that guilty is a murder is simply in the scriptural books such as the Bible and Qur'an. The judge in his book too has whatever one is guilty of as a murder in his book.

In a community a species of birds has some individuals with a different size and others which statement correctly explains how physical differences in beaks would develop?
Explanation:
Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors.
Allopatric speciation (1) occurs when a species separates into two separate groups which are isolated from one another.
Each species develops differently based on the demands of their unique habitat or the genetic characteristics of the group that are passed on to offspring.
When small groups of individuals break off from the larger group and form a new species, this is called peripatric speciation (2).
The main difference between allopatric speciation and peripatric speciation is that in peripatric speciation, one group is much smaller than the other.
Like allopatric and peripatric speciation, different habitats influence the development of different species in parapatric speciation.
Sometimes a species that is formed by parapatric speciation is especially suited to survive in a different kind of environment than the original species.
Sympatric speciation occurs when there are no physical barriers preventing any members of a species from mating with another, and all members are in close proximity to one another.
The two types of maggots are not different species yet, but many scientists believe they are undergoing the process of sympatric speciation.

When mites or fleas live in a dog's fur, what type of relationship is it?
A. Predatory
B. Parasitic
C. Mutualistic
D. Monogamous
When mites or fleas live in a dog's fur, it represents a type of relationship known as a Parasitic relationship. Thus, the correct option is B.
What is the Species relationship?The species relationship may be defined as a process through which the population of one species interacts with the population of another species that lives in the same locality for the purpose of food, space, and shelter.
A parasitic relationship is when one group of organisms known as parasites live on another group of organisms known as hosts and negatively harm it as well as possibly induce death.
The same principle is applied to the mites or fleas that live on dogs' fur. These species gradually cause disease in dogs using hosts machinery and provoking death.
Therefore, when mites or fleas live in a dog's fur, it represents a type of relationship known as a Parasitic relationship. Thus, the correct option is B.

During the metaphase, chromosomes are taken to the equatorial plane, were they randomly line up. Option B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
What is the metaphase?
Metaphase is one of the cell division stages that follows the prophase and precedes the anaphase.
During this phase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes randomly line up.
Once aligned, each chromatid joins with a microtubule of opposites poles and gets ready to go through the anaphase. Sister chromatids are held together until they reach the Anaphase.
Since chromosomes in this stage are well defined and can be observed in detail under the microscope, they are used to create karyotypes and identify chromosomal abnormalities.
These chromosomes have the typical X shape.
Among the options, the one that correctly describes the metaphase is Option is B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
